Reabilitação de dente com hipoplasia de turner: relato de caso / Rehabilitation of tooth with Turner's hypoplasia: Case report

Os defeitos de esmalte são alterações qualitativas ou quantitativas na estrutura dentária, que originam-se de fatores sistêmicos, locais ou genéticos. A hipoplasia de Turner é um defeito na espessura do esmalte localizado cuja etiologia decorre de um traumatismo ou infecção periapical presente no dente decíduo predecessor, afetando o desenvolvimento do dente permanente. O objetivo do presente estudo foi apresentar um caso clínico de paciente infantil com dente hipoplásico de Turner em pré-molar, que tornou-se não vital sem que houvesse lesão de cárie ou trauma adicional. Em razão das características clínicas e radiográficas do dente afetado, bem como do risco de cárie e do comportamento cooperador da paciente, optou-se pela reabilitação do elemento afetado por meio de tratamento endodôntico e de restauração semidireta em resina composta. Torna-se de fundamental importância o conhecimento da etiologia e a realização de um exame clínico e radiográfico minucioso visando ao diagnóstico precoce e à elaboração de um plano de tratamento adequado para todos os defeitos de desenvolvimento do esmalte, incluindo-se a hipoplasia de Turner, cujo tratamento dependerá da severidade da alteração, do comportamento do paciente e do risco de cárie. Sugere-se a realização de estudos que associem a microestrutura do esmalte hipoplásico com a ausência de vitalidade pulpar.

Enamel defects are qualitative or quantitative changes in the tooth structure originating from systemic, local, or genetic factors. Turner's hypoplasia is a defect in the thickness of the localized enamel whose etiology arises from trauma or periapical infection in the predecessor deciduous tooth, affecting the permanent tooth's development. The objective of the present study was to present a clinical case of a child patient with a hypoplastic Turner premolar tooth, which became non-vital without the occurrence of caries, or additional trauma. Due to the affected tooth's clinical and radiographic characteristics, the risk of cavities, and the patient's cooperative behavior, it was decided to rehabilitate the affected element through endodontic treatment and semidirect restoration in composite resin. It is of fundamental importance to know the etiology and carry out a thorough clinical and radiographic examination aiming at early diagnosis and the development of an adequate treatment plan for all enamel developmental defects, including Turner's hypoplasia, whose treatment will depend on the severity of the change, the patient's behavior and the risk of caries. Studies are suggested to be carried out that associate the microstructure of hypoplastic enamel with the absence of pulp vitality.

Resumen: Consenso internacional para la nomenclatura y clasificación de la válvula aórtica bicúspide congénita y su aortopatía, con fines clínicos, quirúrgicos, intervencionistas y de investigación / Summary: International consensus statement on nomenclature and classification of the congenital bicuspid aortic valve and its aortopathy, for clinical, surgical, interventional and research purposes

resumen está disponible en el texto completo

Abstract This consensus of nomenclature and classification for congenital bicuspid aortic valve and its aortopathy is evidence-based and intended for universal use by physicians (both pediatricians and adults), echocardiographers, advanced cardiovascular imaging specialists, interventional cardiologists, cardiovascular surgeons, pathologists, geneticists, and researchers spanning these areas of clinical and basic research. In addition, as long as new key and reference research is available, this international consensus may be subject to change based on evidence-based data1.

Advances in cardiovascular diseases in children with Turner syndrome / 国际儿科学杂志

Turner syndrome（TS），a condition among females with a karyotype containing one X chromosome and complete or partial absence of the second sex chromosome，affects 20～50 in 100 000 newborn girls. Congenital or acquired cardiovascular diseases are present in about half of patients with TS. The congenital defects occur in about 25%～50% of TS patients；aortic dilatation as an important risk factor for aortic dissection is common in adult patients with TS. Furthermore，arrhythmias are found more frequently in patients with TS. A higher prevalence of hypertension in children and adolescents with TS has also been reported，and the application of 24h ambulatory blood pressure monitoring may facilitates the diagnosis of hypertension among these children and adolescent.Thus，active health education，correct follow-up and timely intervention are crucially needed.

Outcome analysis of functional mitral regurgitation after transcatheter aortic valve replacement in patients with severe bicuspid aortic stenosis / 复旦学报（医学版）

Objective To explore the relationship between the types of bicuspid aortic valves(BAV)and the outcome of functional mitral regurgitation(FMR)and the affecting factors of FMR.Methods From Jun 2018 to Sep 2022,patients with severe BAV aortic valve stenosis(AS)complicated with FMR underwent post transcatheter aortic valve replacement(TAVR)in Zhongshan Hospital,Fudan University were retrospectively analyzed.The baseline information and imaging data of different BAV patients were collected.Logistic regression was used to analyze the factors affecting the outcome of FMR(improvement and non-improvement).Result A total of 100 patients with TAVR were included,including 49 patients with type 0 of BAV and 51 patients with type 1 of BAV.Compared with patients of type 1,patients of type 0 had younger age[(72.78±6.09)y vs.(77.00±8.35)y,P=0.050],lower male ratio(47%vs.73%,P= 0.009)higher BMI[(23.19±2.62)kg/m2 vs.(21.99±3.13)kg/m2,P=0.041],and lower incidence of aortic regurgitation(69%vs.92%,P=0.040).Compared with the non-improvement group,the improvement group had a lower incidence of coronary heart disease(5%vs.18%,P=0.042),higher incidence of pulmonary hypertension(20%vs.2%,P=0.007),larger left ventricular diastolic diameter[(51.98±6.74)mm vs.(48.04±7.72)mm,P=0.009]and higher maximum flow velocity[(4.86±0.95)cm/s vs.(4.47±0.75)cm/s,P= 0.023]of the aortic valve.The results of Logistic regression analysis showed that preoperative pulmonary hypertension,left ventricular end-diastolic diameter and maximum valvular flow velocity of BAV patients were the potential affecting factors of FMR improvement after TAVR.Conclusion No significant difference was found in FMR improvement between BAV patients of type 0 and type 1 after TAVR.For BAV patients with AS,preoperative pulmonary hypertension,larger left ventricular end-diastolic diameter,and faster aortic valve flow velocity were associated with higher FMR improvement rate.

A Successful Aortic Valve-Sparing Root Replacement Operation (Reimplantation) to Repair Root Dilatation and Aortic Valve Regurgitation after a Ross Procedure / 日本心臓血管外科学会雑誌

We report a successful case of aortic valve-sparing root replacement for dilated aortic root after a Ross procedure. A 29-year-old male underwent a Ross procedure when he was 11 years old for congenital aortic bicuspid valve. The right ventricular outflow tract was reconstructed using an autologous pericardium as a single leaflet valve. Aortic root dilatation and moderate aortic valve regurgitation were noted. Further investigation with enhanced computed tomography and ultrasonic cardiography revealed good quality of leaflets and sufficient geometric height, and aortic valve-sparing root replacement was performed. In addition, we performed pulmonary valve replacement with a biological valve. The post-operative course was uneventful and the patient was discharged after 8 days with a completely controlled aortic valve regurgitation. No recurrence of aortic valve regurgitation was observed 1 year later. Because surgical outcomes of congenital heart diseases have improved and more patients have an increasing life expectancy, several other problems were revealed, such as the occurrence of aortic root dilatation after a Ross procedure. Aortic roots may dilate due to arterial pressure; however, valve-sparing procedures may be performed if the volume of the leaflets is sufficient.

Analysis of related factors of new-onset conduction disturbance after transcatheter aortic valve replacement with self-expanding valve / 中国介入心脏病学杂志

Objective To investigate the baseline clinical characteristics,ascending aortic root anatomical characteristics,and related factors of the surgical strategy of patients with new-onset conduction disturbance(NOCD)after transcatheter aortic valve replacement(TAVR)with self-expanding valve(SEV)implantation.Methods A retrospective study was conducted on 245 patients who underwent TAVR at the Xiamen Cardiovascular Hospital Xiamen University between December 2014 and November 2022.According to the inclusion and exclusion criteria,167 patients with SEV implantation during surgery were continuously included.They were divided into tricuspid aortic valve group(TAV group,113 cases)and bicuspid aortic valve group(BAV group,54 cases)according to aortic valve morphology.The TAV group was divided into NOCD group(43 cases)and non NOCD group(70 cases)according to postoperative electrocardiogram characteristics.The BAV group was divided into NOCD group(16 cases)and non NOCD group(38 cases).Collect clinical data such as preoperative electrocardiogram and ascending aortic root CT angiography from patients.Results The right-non valvular calcification quantification(P=0.005)in the non-NOCD group was significantly greater than that in the NOCD group,but the aortic angle(P=0.002)was smaller in TAV patients.Multivariate analysis suggested that the risk of NOCD after TAVR is reduced by 2.6％for every 10 mm3 increase in right-non valvular calcification in patients(OR 0.974,P=0.039),the risk of postoperative NOCD nearly 7.3％for every degree increase in aortic angulation(OR 1.073,P=0.003).In BAV patients the increase of the risk of NOCD after TAVR is nearly 3.3％for every l ms increase in preoperative PR interval(OR 1.033,P=0.041),the risk of NOCD is reduced by 6.6％for every 10 mm3 increase in calcification quantification in the right coronary valve area(OR 0.934,P=0.013).Conclusions In TAV patient,right-non valvular calcification may have a protective effect on the cardiac conduction system,but a larger aortic angle increases the risk of NOCD.In BAV patients,a longer preoperative PR interval is a risk factor for NOCD,and the right coronary valve area may protect the cardiac conduction system.

Ascending Aortic Progression After Isolated Aortic Valve Replacement Among Patients with Bicuspid and Tricuspid Aortic Valves

ABSTRACT Objectives: The aims of the present study were to compare the long-term outcomes for ascending aortic dilatation and adverse aortic events after isolated aortic valve replacement between patients with bicuspid aortic valve (BAV) and tricuspid aortic valve ( TAV). Methods: This retrospective study included 310 patients who had undergone isolated aortic valve replacement with an ascending aorta diameter ≤ 45 mm between January 2010 and September 2021. The patients were divided into BAV group (n=90) and TAV group (n=220). The differences in the dilation rate of the ascending aorta and long-term outcomes were analyzed. Results: Overall survival was 89 ± 4% in the BAV group vs. 75 ± 6% in the TAV group at 10 years postoperatively (P=0.007), yet this difference disappeared after adjusting exclusively for age (P=0.343). The mean annual growth rate of the ascending aorta was similar between the two groups during follow-up (0.5 ± 0.6 mm/year vs. 0.4 ± 0.5 mm/year; P=0.498). Ten-year freedom from adverse aortic events was 98.1% in the BAV group vs. 95.0% in the TAV group (P=0.636). Multivariable analysis revealed preoperative ascending aorta diameter to be a significant predictor of adverse aortic events (hazard ratio: 1.76; 95% confidence interval: 1.33 to 2.38; P<0.001). Conclusion: Our study revealed that the long-term survival and the risks of adverse aortic events between BAV and TAV patients were similar after isolated aortic valve replacement. BAV was not a risk factor of adverse aortic events.

Fundamento: los avances en la imagenología y su implementación en la Odontología permiten lograr mejores tratamientos. Objetivo: describir los resultados de la técnica ortoradial vs técnica paralela en la identificación de conductos de primeros premolares superiores y primeros molares inferiores. Métodos: estudio observacional, descriptivo y transversal en pacientes con necesidad de tratamiento de conductos de primeros premolares superiores o primeros molares inferiores, que acudieron a la Unidad de Atención Odontológica de la Universidad Regional Autónoma de los Andes en el periodo abril-agosto de 2019. La muestra la constituyeron 62 pacientes, separados en dos grupos: premolares superiores (n=30) o primeros molares inferiores (n=32) y ambos en otros dos grupos según técnica empleada (técnica paralela y técnica ortoradial). Resultados: en los primeros premolares superiores la técnica ortoradial mostró mejores resultados que la paralela para obtener imágenes precisas (100 % vs. 20 %). En los primeros molares inferiores, la técnica ortoradial mostró resultados superiores a la técnica paralela para el conducto mesiolingual (93,75 % vs 31,25 %) y conducto disto lingual (31,25 % vs 12,5 %). La elongación de las raíces predominó en la técnica ortoradial (n=8), al igual que la superposición dental (n=10). Conclusiones: la técnica ortoradial mostró resultados superiores al momento de localizar tanto el conducto vestibular y palatino en los primeros premolares superiores como para el conducto mesiolingual y el conducto distolingual. La elongación de las raíces se observó en mayor cuantía en la técnica ortoradial, al igual que la superposición dental.

Foundation: advances in imaging and its implementation in Dentistry allow for better treatments. Objective: to describe the results of the orthoradial technique vs parallel technique in the identification of upper first premolars canals and lower first molars. Methods: observational, descriptive and cross-sectional study in patients in need of root canal treatment of upper first premolars or lower first molars, who attended the Dental Care Unit of the Andes Regional Autonomous University from April to August 2019. The sample consisted of 62 patients, separated into two upper premolar groups (n=30) or lower first molars (n=32) and both into two other groups according to the technique used (parallel technique and orthoradial technique). Results: in the upper first premolars, the orthoradial technique showed better results than the parallel technique to obtain accurate images (100% vs. 20%). In the lower first molars, the orthoradial technique showed superior results to the parallel technique for the mesiolingual canal (93.75% vs 31.25%) and distolingual canal (31.25% vs 12.5%). Root elongation predominated in the orthoradial technique (n=8), as did dental overlap (n=10). Conclusions: the orthoradial technique showed superior results when locating both the buccal and palatine canal in the upper first premolars and for the mesiolingual canal and the distolingual canal. Root elongation was observed to a greater extent in the orthoradial technique, as was dental overlap.

Minimally Invasive Surgery with the Bentall-De Bono Technique. Initial Experience at Hospital Italiano de Buenos Aires / Cirugía de Bentall de Bono por abordaje miniinvasivo. Experiencia inicial del Hospital Italiano de Buenos Aires

ABSTRACT Background : Cardiac surgery avoiding full sternotomy began to emerge in the 1990s with the first hemi-sternotomies and mini-thoracotomies. Aortic valve and root surgery is one of the most common procedures in our field. In this paper, we analyze our experience in minimally invasive cardiac surgery (MICS) for the aortic root with the Bentall-De Bono technique (MICS-Bentall). Objective : To analyze the surgical results in the first 10 patients underwent a MICS-Bentall procedure at our site. Materials and Methods : A retrospective observational study was carried out including patients with valve disease and aortic root dilation who underwent a surgery with the MICS-Bentall procedure in a tertiary care hospital from December 2019 to December 2020. Continuous variables were expressed as mean and standard deviation or median and interquartile range according to the observed distribution. Categorical variables were expressed as absolute and relative frequency. Results : Out of 165 patients undergoing aortic root surgery, 10 patients were included. Mean age was 56 ± 17.03 years, 70% male; all cases were elective. Median (interquartile range, IQR) STS PROM % was 1.48 (1- 2.02). Eighty percent had bicuspid valve. Fifty percent of patients were extubated within 6 hours. In the 30-day follow-up, no death was recorded, and two complications were registered: one patient experienced atrial fibrillation without hemodynamic decompensation and another a wound infection. The mean hospital length of stay was 5 days. Conclusion : In our experience, MICS using the Bentall technique showed satisfactory results in terms of low perioperative mortality, early extubation, and short hospital stay.

En seguimiento a 30 días no se registraron óbitos, y hubo 2 complicaciones: un paciente presentó fibrilación auricular sin descompensación hemodinámica, y otro, infección de herida. La estadía hospitalaria fue en promedio de 5 días. Conclusión : En nuestra experiencia con MICS con la técnica Bentall se obtuvieron resultados satisfactorios con baja mortalidad perioperatoria, extubación precoz y tiempos cortos de estancia hospitalaria.

Un tipo de válvula aórtica bicúspide poco frecuente / A rare type of bicuspid aortic valve

The bicuspid aortic valve corresponds to the most common valve defect in the general population. This can present asymptomatically as an incidental finding or symptomatically due to valve disease (stenosis and regurgitation), aortopathy, and infective endocarditis. Imaging techniques such as transthoracic and transesophageal echocardiography are fundamental pillars in diagnosis and treatment, determining the need for surgical intervention and the type of surgery to be performed. The case of a young patient with a less frequent bicuspid aortic valve phenotype is presented.

Reemplazo endovascular aórtico en un paciente con enfermedad de válvula aórtica bicúspide / Endovascular aortic replacement in a patient with bicuspid aortic valve disease

Resumen Un varón de 49 años ingresó en la unidad de cuidados coronarios, con antecedentes de miocardiopatía dilatada, con función sistólica del ventrículo izquierdo gravemente deteriorada y estenosis aórtica grave de origen bicúspide, sintomático para síncope, ángor y disnea de reciente diagnóstico. Durante la internación evolucionó con shock cardiogénico que requirió doble soporte inotrópico. Por presentar alto riesgo quirúrgico y elevada probabilidad de rechazo ante un eventual trasplante cardiaco, según sus estudios de histocompatibilidad, se procedió al reemplazo transcatéter de la válvula aortica, con evolución favorable.

Abstract A 49-year-old male with a history of left ventricular systolic function dilated cardiomyopathy and severe symptomatic bicuspid aortic stenosis recently diagnosed (syncope, chest pain and dyspnea) was admitted to the coronary care unit. During hospitalization, he developed cardiogenic shock requiring double inotropic support. High surgical risk and an elevated chance of graft rejection contraindicated surgical replacement or heart transplant. We performed a transcatheter aortic valve replacement with a favorable evolution.

The clinical effect of a combined technical system for bicuspid aortic valves repair / 中国胸心血管外科临床杂志

@#Objective    To summarize the clinical result of a combined technical system for bicuspid aortic valve (BAV) repair. Methods    Patients who diagnosed as BAV and sever aortic regurgitation (AR) underwent a strategy of combined repair technics including annuloplasty, sinus plasty, leaflet plasty, sinus-tubular junction (STJ) plasty depending on anatomy pathological characteristics between October 2019 and January 2021 were enrolled. The clinical data of the patients were analyzed. Results    A total of 17 patients were enrolled. There were 11 males and 6 females with an average age of 18-49 (32.4±13.6) years. Fifteen patients had typeⅠand 2 patients had typeⅡBAV according to Sievers classification. Annuloplasty was applicated in 13 patients, sinus plasty in 8 patients, leaflet plasty in 17 patients, and STJ plasty in 11 patients, respectively. The cardiopulmonary bypass (CPB) time was 95 (84, 135) min, aortic cross-clamping time was 68 (57, 112) min, and the ICU stay time was 17 (12, 25) h. After the operation, mild AR was presented in 14 patients, moderate AR in 1 patient and severe AR in 2 patients. The latter 3 patients underwent second operation under CPB, after then, 1 patient had mild AR and 2 patients had moderate AR. The follow-up time was 13.1±4.6 months. At the latest follow-up, 12 patients had mild AR and 5 patients had moderate AR, and no patient had reoperation. Conclusion    A combined technical system for BAV repair can be used effectively and safely with an acceptable short and middle-term result.

Transapical transcatheter aortic valve replacement in bicuspid aortic valve patients: In-hospital outcomes / 中国胸心血管外科临床杂志

@#Objective    To compare the in-hospital outcomes of transapical transcatheter aortic valve replacement (TA-TAVR) for bicuspid aortic valve (BAV) patients and tricuspid aortic valve (TAV) patients. Methods    Patients (including BAV and TAV patients) who underwent TA-TAVR with the J-ValveTM in West China Hospital from July 2014 to July 2020 were included consecutively. The clinical outcomes of the patients were analyzed. Results    A total of 354 patients were included in the study, 75 in the BAV group and 279 in the TAV group. There were 229 males and 125 females with a mean age of 72.2±6.0 years. No death occurred during the procedure, and the overall technical success rate was 97.7%. The all-cause in-hospital mortality rate was 1.4%. Twenty (26.7%) patients with BAV and 46 (16.5%) patients with TAV had mild or higher perivalvular leaks immediately after the procedure. No patients with BAV required permanent pacemaker implantation postoperatively, while 13 (4.7%) TAV patients required permanent pacemaker implantation, with an overall pacemaker implantation rate of 3.7%. One (1.3%) BAV patient and 7 (2.5%) TAV patients developed acute kidney injury postoperatively. One (1.3%) BAV patient and 1 (0.4%) TAV patient developed peri-operative myocardial infarction. The average postoperative hospital stay was 7.6±3.6 d for BAV patients and 8.6±6.1 d for TAV patients. There was no statistical difference in primary or secondary in-hospital outcomes between BAV and TAV patients (P>0.05). Conclusion    Compared to TAV patients, BAV patients have similar in-hospital outcomes, with a low incidence of adverse clinical outcomes, which provides preliminary evidence for its implementation in Chinese patients with a high proportion of BAV.

Research progress of application of transcatheter aortic valve replacement in the bicuspid aortic valve stenosis / 中国胸心血管外科临床杂志

@#Patients with bicuspid aortic valve (BAV) are characterized by asymmetric anatomy, severe calcification and combined aortic dilatation. Compared with tricuspid aortic valve stenosis patients, patients with BAV stenosis confront with greater surgical risks in transcatheter aortic valve replacement (TAVR), including paravalvular leak, aortic valve rupture, coronary artery obstruction, atrioventricular block and so on. However, with the advent of new generation of prosthetic valves and optimization of surgical strategies, several studies have shown that TAVR is safe and effective in the treatment of BAV stenosis. Therefore, we aim to provide an overview of the use of TAVR in patients with BAV stenosis.

Acute Aortic Dissection Masquerading a Rare Type of Congenital Bicuspid Aortic : A Case Report

Acute aortic dissection on bicuspid aortic valve (BAV) type 0 is a rare especially in young masculine. Risk factors like smoking and intensive sport activities can hasten their apparition especially in non-diagnosed population. Trans thoracic echocardiography is very important in the diagnosis of BAV whereas Angio CT scan helps to confirm acute aortic dissection. Treatment is based on surgery for type A Stanford classification for acute aortic dissection. We report a rare case of acute aortic dissection masquerading a rare type of BAV, type 0 in a young sportive male with no history of heart disease who presented for the first-time with acute chest pain after lifting a heavy weight metal at the complex sport center. Patient was initially placed on medical treatment before surgery for heart valve and root replacement (Bentall procedure).

Successful Surgical Treatment of Coronary Aneurysm, Ascending Aortic Aneurysm, and Bicuspid Aorta for a Kawasaki Disease Patient

Abstract Kawasaki disease was first reported in 1967, and it was classified as an autoimmune vasculitis of the small and medium arteries. It is a self-limiting condition that occurs mostly in childhood, but it may involve complications — such as coronary artery aneurysms, myocardial ischemia, and arrhythmias — with significant morbidity and mortality that occur later in life. In this article, we present the association of an ascending aortic aneurysm with bicuspid aortic disease in addition to coronary aneurysm in a 55-year-old patient diagnosed with Kawasaki disease.

Aortic valve repair: An exciting journey / Reparación valvular aórtica: una experiencia emocionante

Abstract Aortic valve repair has become an attractive alternative to aortic valve replacement in most of the patients with aortic insufficiency. To improve reproducibility and durability "geometric anatomy" of the valve has been developed to guide the repair. Expert centers were able to publish remarkable short- and long-term results for aortic valve sparing procedures. Therefore, data comparing composite valve grafting and aortic valve sparing procedures revealed similar early mortality. Also, late mortality, thromboembolism, stroke and bleeding risks were significantly lower in patients undergoing aortic valve repair and late durability was equivalent1. However, the complexity of the procedures makes aortic valve repair difficult to be adopted into daily surgical practice. Accordingly, starting your own aortic valve repair program requires conviction, training, facilities, quality control and a well structured heart valve team to let your program succeed.

Resumen La reparación valvular aórtica se ha convertido en una alternativa atractiva al reemplazo, en la mayoría de pacientes con insuficiencia aórtica. Para mejorar la reproducibilidad y la durabilidad, se ha desarrollado una "anatomía geométrica" de la válvula para guiar la reparación. Los centros expertos han publicado resultados notables a corto y largo plazo en preservación valvular aórtica. Además, los estudios que compararon el cambio valvular por tubo valvulado con los procedimientos de preservación valvular, mostraron una mortalidad temprana similar, con riesgos de mortalidad tardía, como tromboembolia pulmonar, accidente cerebrovascular y hemorragia, significativamente menores en los pacientes sometidos a reparación valvular aórtica, con una durabilidad tardía equivalente1. Sin embargo, la complejidad de los procedimientos dificulta la adopción de la reparación valvular aórtica en la práctica diaria. En consecuencia, comenzar un programa de reparación valvular aórtica requiere convicción, capacitación, instalaciones, control de calidad y un equipo bien estructurado para que sea exitoso.

Tratamiento en un tiempo quirúrgico de una coartación aortica asociada a valvulopatía aórtica bicúspide severa. Reporte de un caso / One stage surgical treatment of aortic coarctation associated with bicuspid aortic valve. Report of one case

Percutaneous surgery is the treatment of choice of isolated aortic coarctation in adults However, when there are other heart problems related to aortic coarctation, its surgical management may vary. We report a 41-year-old male presenting with aortic coarctation associated with severe, symptomatic, bicuspid aortic valve lesions and significant left ventricular dysfunction. He underwent open heart surgery for the surgical resolution of these problems. One year after surgery the results are satisfactory with no evidence of postoperative complications and a significant improvement of patient symptoms and left ventricular function.

Transcatheter Aortic Valve Implantation in Bicuspid Aortic Valve with Aortic Stenosis: a Meta-Analysis and Trial Sequential Analysis

Abstract Objectives: Bicuspid aortic valve (BAV) is an important aetiology of aortic stenosis and the use of transcatheter aortic valve implantation (TAVI) has not been fully explored in this cohort. This systematic review and meta-analysis compared the outcomes of TAVI in stenotic BAV against tricuspid aortic valve (TAV). Methods: An electronic literature search was performed in PubMed, MEDLINE, EMBASE, and Scopus to identify all studies comparing TAVI in stenotic BAV versus TAV. Only studies comparing TAVI in BAV versus TAV were included, without any limit on the study date. Primary endpoints were 30-day and 1-year mortality, while secondary endpoints were postoperative rates of stroke, acute kidney injury (AKI), and permanent pacemaker (PPM) requirement. A trial sequential analysis (TSA) was performed for all endpoints to understand their significance. Results: Thirteen studies met the inclusion criteria (917 BAV and 3079 TAV patients). The BAV cohort was younger (76.8±7.43 years vs. 78.5±7.12 years, P=0.02), had a higher trans-aortic valve gradient (P=0.02), and larger ascending aortic diameters (P<0.0001). No significant difference was shown for primary (30-day mortality [P=0.45] and 1-year mortality [P=0.41]) and secondary endpoints (postoperative stroke [P=0.49], AKI [P=0.14], and PPM requirement [P=0.86]). The BAV group had a higher rate of significant postoperative aortic regurgitation (P=0.002). TSA showed that there was sufficient evidence to conclude the lack of difference in PPM requirements, and 30-day and 1-year mortality between the two cohorts. Conclusion: TAVI gives satisfactory outcomes for treating stenotic BAV and should be considered clinically.
